This invention relates to the field of superhydrophobic anti-icing coating technology, specifically to a low-temperature phase change microcapsule superhydrophobic anti-icing coating and its preparation method. The specific technical solution is as follows: The preparation process involves ultrasonically dispersing superhydrophobic low-temperature phase change microcapsules in an organic solvent, adding an adhesive and a curing agent to the dispersion, stirring at room temperature, uniformly coating a composite layer onto a substrate, and curing to obtain the low-temperature phase change microcapsule superhydrophobic anti-icing coating. This invention utilizes a tetradecane / dodecyl alcohol binary eutectic phase change core material as an energy storage core material, and forms low-temperature phase change microcapsules by coating silica with interfacial polymerization, thereby achieving permanent curing of the core material, preventing leakage, and extending service life. After superhydrophobic modification, the superhydrophobic low-temperature phase change microcapsules are composited with polydimethylsiloxane to prepare a composite coating with superhydrophobic and latent heat release properties, achieving the purpose of anti-icing.

This invention relates to a lip gel composition for reducing wrinkles and moisturizing, and its preparation method. The lip gel composition, by weight percentage, comprises: 0.5-1.5% dipalmitoyl hydroxyproline, 0.05-0.1% hybrid rose extract, 0.02-0.05% hyaluronic acid microspheres, 15-20% castor seed oil, 0.05-0.1% sunflower seed oil, 0.0005-0.001% β-carotene, 35-41% caprylic / capric triglycerides, and 32-50% octyl-dodecyl alcohol. The hyaluronic acid microspheres are composed of hyaluronic acid encapsulated in castor seed oil. The preparation employs a staged low-temperature mixing process: first, an oil phase carrier is formed at 60-80℃; then, a collagen activator is added for dispersion; and finally, the heat-sensitive active ingredients are integrated at ≤40℃. This solution breaks through the limitations of traditional lip products where efficacy and skin feel cannot be achieved simultaneously. Tests have shown that after 30 days of use, lip lines are reduced by more than 40%, and hydration is increased by more than 60% after 4 hours. Moreover, no synthetic preservatives or synthetic pigments are added throughout the entire process.
